Claims. 1

This invention relates to improvements in illuminated ornamental devicesand more particularly is directed to a heat and light concentratingholder means for confining heat and projecting light passing from anincandescent lamp to a liquid column for forming an illuminated vaporbubbling or unbroken stream display efiect, such as used for trimminChristmas trees or decorative lighting, signs or the like.

Amon the objects of the invention is to generally improve devices of thecharacter described which shall be exceedingly simple in construction,of few parts, which shall be easy to assemble in effective position,which shall be cheap to manufacture, and which shall be practical andefiicient to a high degree in use.

Other objects of this invention will in part be obvious and in parthereinafter pointed out.

The invention accordingly consists in the features of construction,combinations of elements and arrangements of parts which will beexemplified in the construction hereinafter described and of which thescope of application will be indicated in the following claims.

In the accompanying drawings, in which is shown various possibleillustrative embodiments of this invention:

Fig. l is a front elevational view of an assembled unit of a Christmastree lighting unit, shown partly broken away to expose the interior,constructed to embody the invention.

Figs. 2 and 3 are cross sectional views taken on lines 2-2 and 33,respectively, in Fig. 1, and

Fig, 4 is a perspective view, showing the improved heat and lightconcentrating holder removed from the lighting unit.

Referring in detail to the drawing, Ill denotes an illuminatedornamental device adapted to be used to trim a Christmas tree or thelike, having incorporated in the assembly thereof a heat and 7 lightconcentrating holder member iI constructed to embody the invention.

Said holder member I l as seen in Figs. 1 and 4, comprises a sleeveconnector supporting in vertically upright position, a transparent tubebody of glass or other translucent material designated generally as i2,said tube body i2 having an integral closed lower or bottom end I2a andsealed top end I212. The closed bottom end I2a, is fitted into the upperend Ha of said holder member II, so that the lower or bottom tube endI2a is firmly supported in close proximity to a bulb Eta of anincandescent lamp I3, the lamp bulb 53a being fitted up into the lowerend Nb of said holder member II thereby providing a relatively firminterconnecting support or rigid coupling.

The lamp I3 as here shown is mounted in one electric socket lb of aChristmas tree lighting outfit of a well understood construction (notshown).

The tube body l2 may contain a readily vola- 2 V tilizable liquid I4,such as other or wood alcoho but preferably a transluscent liquid whichhas a like relatively normal low boiling point but which isnon-inflammable. The liquid I4 may be placed in the tube body I2 throughthe top end I21) thereof before fusing the latter for hermeticallysealing in liquid I4 therein as shown in Fig, 1. The space I5 above theliquid 14 in the tube body l2 may be evacuated before said tube top endI2b is sealed to permit lowering the boiling point normally required forthe liquid l4. Said space I5 constitutes a condensing and heatdissipating means.

As seen from Fig. l, the invention is shown incorporated in the assemblyof the ornamental illuminated device II] as above described, said sleeveconnecting holder member II being preferably made of any suitablematerial having light conducting properties of a high degree efficiencyas for example quartz, or any well known molded plastic having similarcharacteristics, such as Lucite. The lower end lib of holder member I Imay be provided with spaced wing sections IIc which are inwardly bent tohave rim edge surfaces IId positioned in horizontal alignment withfilament I3b in lamp bulb I311. The upper end I la, of said holdermember I I may be formed or terminate with integral resilient spacedgripper portions I Ie which may also be inwardly bent preferably insuitable angular relation to the axis of the tube body I2 and liquidcolumn I4 so that light beams from the glowing lamp filament [3b whichare caught bysaid edges I Id are transmitted longitudinally through theholder II and projected from terminating rim edge surfaces II of gripperportions He into the liquid column M, as is clear from Fig. 1.

In practising the invention, assume an electric socket I6 is provided orarranged for decorative display lighting purposes and connected to asuitable power supply source (not shown) in the well understood mannerfor lighting the lamp I3. Heat and light radiated from the lamp filament[3b may be made effective to cause the generating of vapor I'l either inform of a continuous fiow of bubbles, or in an unbroken stream currentthrough the liquid column I l. The sleeve holder II which mounts thetube body I2 on the lamp bulb I3a serves to guide and confine the heatconducting medium, namely, air therebetween that a minimum of heatproducing source will be necessary. The light transmission provided bythe improved construction of said sleeve holder II above described,increases the light available by projecting therethrough light beamsdirectly from the lamp filament I3a into the liquid column I4, inaddition to light beams from lamp filament I31) which are projectedlongitudinally the length of theholder II into flowing bubbles orcurrent I! as seen from the exment I3b by two separate paths one ofwhich,

by-passes the bottom tube end I20; and is transmitted through holdermember II is particularly desirable when a bubble or currentformingmeans forms an obstruction of the direct rays from the lampfilament I3b, or is opaque to the direct passage of light in which casesubstantially all the illumination to said bubble or current flow I! iscircuited through said sleeve member II as described above and isclearly'shown in the draw ing.

By coloring the material forming sleeve mem- :ber II a wide range ofcolor efiects are made available beside the variegated lighting,produced at and around the openings in the regions of the spaced gripperportions I Ia and spaced wing sections IIc.

It is also to be understood that holder member II may be made to conformto any requirement of design desired such as of straight lin contour orof bulbous character. This feature is made possible because the lightconducting ma- 7 terial forms a path through said holder member I I andis not affected by the shape thereof intermediate rim edge surfaces lI fof gripper portions He and rim edge surfaces I Id of wing sections I I0.

It also is contemplated in practising the invention described herein toapply same to holder fitting such as shown in Patent No. 2,378,934,issued June 26, 1945, to Joseph H. Kloner. In such case the incandescentlamp is mounted at right angles with respect to the tube body, suchholder fitting being constructed of molded plastic, as for exampleLucite and is formed to transmit light from the lamp filament throughthe molded plastic material as well as directly through the extensionholder supporting the tube body in th same manner as above described formember II.

It is thus seen that there is provided an improved heat and lightconcentrating holder means :of the character described in which theobjects of the invention are achieved and which are well adapted to meetall conditions of practical use.

As various possible embodiments may be made as illustrative and not in alimiting sense.
